no video on iMac g4 20
I bought an Imac g4 20"1,25 Ghz, for a few euro's, with no video on the screen.
The guy told me: i think the video issue is about a cracked video-cable. Oke, the risk was mine.
Well, it could be possibly anything of course, so i went on searching for the problem.
Indeed, no video, not even a grey display.
Bought a mini-vga>vga cable: but alas, still no success.
I was able to start in Target mode hooking it up to my powerbook g4, the 80GB HD appeared on the screen
was able to read it and removed personal things from the previous owner. Imac starts up, sounds the chime, reads DVD's, so there is a little bit of hope....
what i’m gonna do is: 1 replace pram battery first and at the same time inspect the video connection of the logicboard, upgrade ram (original 256MB now). if that does not work out, remove the neck, check the inverter, etc.
to be continued (i guess....)
every suggestion how to solve this prob and make a wonderful iMac is more them welcome.

Update
Hello there,
things are getting better.
with a mini-vga tot vga adapter from Apple (thrird party adapter did not work) i do have a picture on an external lcd-monitor.
I added 1 GB ram and an airport card, installed Leopard (runs fast enough)
but still no picture on the internal lcd, which is recognized by the way,
not a sign that it is trying to give a picture, it stays black, with a torchlight there is nothing to see (in case the inverter is broken.
(but mic works, sleep light is blinking when activated),
My question is: does it make sense to open the lcd housing and check whether the cables are properly connected, or do i have to open the Imac, and check the LB connections (next step).
any advice is more than welcome.

Update
Still working (but not every day :) on this Imac g4 20. Will the video cable from an Imac g4 17" fit into the 20" version? Or will it be possible to replace the 20" with a 17" LC from Imac g4?
